`|•Giyu Tomioka

In one of your missions as Hashira, you had ended up deaf because of a demon and you had to learn sign language to be able to communicate, you asked some pillars who were the ones you talked to the most not to say anything, The only one you didn't socialize with was Giyu, you two had to go on a mission together and for the first time he spoke to you but you hadn't heard him or answered him, that bothered him a little, while they were fighting with a demon, he yelled at you that he was behind. There was a demon of yours and in the end he had to kill the demons, he was scolding you until he noticed that you seemed confused as if you didn't understand, he gently touched your ear twice and shook his finger, in a way that asked you if you were deaf@
